Abstract (en)

[origin: WO0167798A1] Methods and apparatus for providing a hierarchical mobility management function for routing packets to mobile nodes are provided. The hierarchical mobility management function may be placed anywhere within the network and provide efficient use of IPv6 addresses. A node implementing the hierarchical mobility management function receives packets intended for the mobile node and routes the packets to the mobile node's current address. Load sharing of packets intended for a mobile node may be implemented across several access routers. Additional, bi-casting of packets is provided to allow for seamless handoff of the mobile node as it switches from one access router to another access router.
